The origin of Superheroes: Night Eagle
https://en.wikipedia.org/wiki/Night_Eagle
Night Eagle is a fictional character from DC Comics. She first appears in The Adventures of Superman #586 (December 2000), and was created by J.M. DeMatteis and Mike Miller. She is a shaman of sorts, with a kinship with owls.
When Satanus tried to corrupt Metropolis with dark magic, Superman tried to intervene, but was overwhelmed by a powerful spell from the demon. As globes of dark power engulfed Superman, a flock of barn owls flew in and destroyed the globes. Superman looked up to see a Native American woman in an owl-like costume, who told Superman to "You can no longer trust your eyes, you can only trust your heart", before she vanished.
Later, Superman followed an owl to a building, on which the woman stood, and she introduced herself as "Night Eagle". As magical foes and demons began attacking Metropolis, she would guide him on how to beat them. But when Satanus threatened to destroy the "soul of the city", Superman offered his soul in exchange. The result was that Superman was evil, as his soul was trapped in Hell.
Night Eagle appeared to Lois Lane and helped her enter Hell. There Lois helped Superman free himself, and the two defeated Satanus. Night Eagle then vanished, but not before her face became turned in to the face of Satanus's sister, Blaze. Night Eagle's current status and identity are unknown.
